Description Ian Springer 2011-06-29 20:55:34 UTC 
From mazz: I would BZ that and indicate that its because there was no avail data
 - probably an easy NPE fix.

Here's the stack trace (unfortunately a js stack since it's from prod mode):

Comment 1 Ian Springer 2011-06-29 20:58:05 UTC 
I think this can be reproduced as follows:

1) setup a new Agent on machine X and allow its platform to be discovered
2) stop the Agent
3) import the Agent's platform
4) the platform should have unknown avail since the Agent is down
5) go to the platform's Inventory>Agent subtab

master commit 29b542700591bb3b481479671341c70447d53874

Test Note: Use Ian's repro steps above
Comment 3 Sunil Kondkar 2011-08-24 09:06:57 UTC 
Verified on build#334 Version: 4.1.0-SNAPSHOT Build Number: d686a21)

Followed the steps. NPE is not observed on the platform's Inventory>Agent subtab.

Marking as verified.
